TRUNK-FASTENER.

Specification of Letters Patent.

Patented Mar. 3, 1914.

Application filed February 10, 1913. Serial No. 747,399.

To all whom it may concern Be it known that I, SARKIS MELEDONIAN, a citizen of the United States, residing Seattle, in the county of King and State of lVashington, have invented certain new and useful Im rovements in Trunk-Fasteners, of which t e following is a specification.

My invention relates to trunk fasteners,

and embodies a band encircling the trunk,

and a novel lock which performs the dual function of locking the trunk lid and firmly drawing said band around the trunk, so that the whole trunk is tightly bound together. In order that the invention may be fully understood, reference will now be made to the accompanying drawing, in which:

Figure 1 is an end elevation of a trunk provided with my device. Fig. 2 is an enlarged front elevation partly iii-section, of the lock removed from the trunk. Fig. 3 is a section of the lock on line IIIIII of Fig. 2, showing said lock in position on the front of the trunk, also a portion of the band which embraces the trunk. Fig. 4L is a broken vertical section of that portion of the lock embodying the tumblers and the cylinder, also a portion of the key for controlling the lock. Fig. 5 is a broken, horizontal section on line V-V of Fig. 2. Fig. 6 is a broken, horizontal. section on line VI-VI of Fig. 2. Fig. 7 is a detail elevation of the key. Fig. 8 is an inverted plan view of the cylinder. 1 designates the trunk body, 2 the trunk lid, and 3 the band which embraces the trunk and tightly binds the same together.

Band 3 extends freely through clips 3 on the trunk, and is provided at its rear side with a take-up device 4 having right andloft threads engaging similar threads in the enlarged portions 5 of the band. The upper end of the band 3 is provided with an ear 6, and its lower end is secured to the front of the trunk body by a rivet 7.

The frame of the lock proper consists of an upper hasp member 8, and a lower body member 9, the former being firmly secured to the lid of the trunk at the place where the usual hasp is secured, and the latter to the body of the trunk where the lock is usually secured.

The hasp member 8 has a centrally-disposed vertical groove 10, through which the upper portion of the band 3 freely extends. Said hasp member also has a tongue 11 at its lower end which enters a corresponding recess in the body member 9, and thus tends to hold the two members of the lock frame in vertical alinement.

12 designates a pair of hooks depending from the lower end of the tongue 11 and adapted to engage a pair of latch members 13 horizontally and slidably arranged in the body member 9, Fig. 2. Latch members 13 are yieldingly held in engagement with the hooks 12 by an expansion spring 14 interposed between the adjacent ends of the latch members, the sliding movements of which latter are limited by a pair ofpins 15, fixed in body member 9 and extending transversely through longitudinal slots 16 in said latch members.

The body member 9 has a centrally-disposed, upwardly-extcnding tubular boss 17, internally-tln'eaded to receive the lower threaded end of the lock bolt 18, which ex-.

tends loosely through car 6 and is provided intermediate its ends with a peripheral shoulder 19, adapted to press downward upon said ear and draw the band 3 tightly around the trunk when lock bolt 18 is screwed down into the boss 17, as shown on Figs. 2 and The lock bolt 18 is provided at its upper end with a circular head 20, having an irregular slot 21 extending transversely therethrough to receive the lower portion of the key 22, which is of corresponding shape to enter said slot. There is an opening 23 at each end of slot 21 to admit prongs 24. at the lower corners of the key 22. Openings 23 are also provided to admit to slot 21 any two diametrically-opposed tumblers 25, of a circular series, longitudinally-movable in a cylinder 26, firmly secured by a screw 27, in a central, longitudinal bore 28, extending through the hasp member 8 to receive the lock bolt 18, the cylinder 26, and a number of other elements hereinafter specified. The lower portion of bore 28 communicates with an opening 29, extending through the rear lower portion of the hasp 8 to admit ear 6, Fig. 3.

Each plunger 25 is located in a chamber 30 extending through the cylinder26, and has an enlarged lower terminal 31 to prevent it from being forced through the reduced upper end of said chamber by an expansion spring 32, interposed between the lower end of the tumbler and an annular plate 33. Plate 33 is secured to the lower end of cylinder 26 to close the lower ends of chamhere 30.

Plate 33 rests upon a shoulder 34 at the lower end of opening 28 to relieve the screw 27 of the shearing strain to which it would otherwise. be subjected by the downward pressure exerted upon the lock bolt 18 by a large expansion spring 35, whereby the head 20 of said lock bolt is normally seated upon the upper end of the cylinder 26. The upper end of spring 35 bears against the lower portion of a key guide 36, the circular shoulder 37 of which is held in engagement with a collar 38, fixed in the hasp member 8 at the upper end of bore 28. The key guide 36 has a slot 39 to admit key 22, the lower portion of which slot is normally closed by a pair of oppositely-disposed, substantially V-shaped springs 40 which bear against opposite sides of the key and form a bearing therefor when said key is passed through the slot 39. Spring 40 normally conceals slot 21., so that it will be, practically, impossible to pick the lock. H

lVhen the lid of the trunk is lowered to closed position, and the lower end of the lock bolt 18 contacts boss 17, it will be pushed upward thereby against the pressure of spring 35, which yields sutiiciently to permit complete closure of the lid. The lid may then be locked in closed position by inserting the proper key through slot 39, and into slot 21 which operation depresses the two upwardly projecting tumblers to a level with the top of cylinder 26. The lock bolt 18 is then screwed into boss 17 by rotating the key in the proper direction. As the lock bolt descends it carries ear 6 therewith and thus firmly draws band 3 around the trunk. After thelock bolt 18 has been screwed into boss 17, the desired distance, the key is withdrawn and the lock bolt 18, is then secured from further rotation by the entrance into openings 23 of the two plungers which happen to register therewith. To unlock the trunk it is only necessary to insert the key and rotate the lock bolt in the opposite direction.

Having thus described my invention what I claim and desire to secure by Letters Patent, is:

1. In a device of the character described, a lock consisting of a hasp member and a body member which latter has an'internallyr fasten the two members of the lock together, 7
